Hi all,

Today's linux-next merge of the drm tree got a conflict in:

drivers/firmware/qcom/Kconfig

between commits:

618aedff70fbe ("firmware: QCOM interfaces should depend on ARCH_QCOM") 50508d3e0abd8 ("firmware: qcom: scm: Hide QCOM_SCM instead of depending on ARCH_QCOM")

from the qcom tree and commit:

8fecd3194de33 ("firmware: QCOM interfaces should depend on ARCH_QCOM")

from the drm tree.

I fixed it up (see below) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts.
